Tectonic Summary

From the USGS Event Page:
The November 13, 2016 M7.8 earthquake in North Canterbury, New Zealand, occurred as the result of shallow oblique-reverse faulting on or near the boundary between the Pacific and Australia plates in South Island, New Zealand.

UNAVCO Response

Borehole Strainmeter Data
In response to the M7.8 earthquake 7.8 earthquake 53km NNE of Amberley, New Zealand on 2016-11-13 11:02:56 (UTC), UNAVCO has processed high rate one-sample-per-second (1-sps or 1 Hz) borehole strainmeter data from all borehole strainmeters in the Plate Boundary Observatory (PBO). The fully processed 1-sps borehole strainmeter (BSM) dataset spanning the time period of this event is now available at http://borehole.unavco.org/bsm/earthquakes/20161113_Amberley_NewZealand/.

The Nevada Geodetic Laboratory produces rapid GPS/GNSS time series for all available GPS data, globally. The ultra-rapid GPS plots of five-minute solutions automatically update every hour. For New Zealand, this includes data from IGS stations and also a much denser data set from networks maintained by Land Information New Zealand (LINZ) and GeoNet.
